Crazy Affixes?

i know it's unofficial, but in the patch 15 update notes for the AH, i noticed "Damage_Percent_Bonus_Vs_Elites - Bonus vs Elites". This is a pretty unique and specific bonus for an item to have, and when combined with some of the new elite/champion skills like waller and vortex, it looks like blizz got pretty creative with their affixes. i'm excited to see how much new stuff they came up with. Any thoughts about items with added damage for specific monster types, or guesses at other strange affixes?
